CORN-PLANTER.

SPECIFICATION forming part of Letters Patent N 0. 784,353, dated March '7, 1905. Application tiled October 28, 1904. Serial No. 230,403.

To all IUI'MHH/ it 722/667] concern.-

Be it known that we, HERMAN SCHIELKE, of Cleveland, ()uyahoga county, Ohio, and ED- UAPJ) STEINMANN, of Davenport,Scott county, Iowa, both citizens of the United States, have invented certain new and useful Improvements in Corn-Planters, of which the following is a full, clear, and exact description.

Our invention relates to corn-planters; and its object is to dispense entirely with the necessity of wires and the devices thereon for actuating the seed-distributing mechanism of the hopper of the machine and to accomplish the same result by a simple mechanism which is carried by and constitutes part of each machine, will accommodate itself to the nature of the ground upon which it operates, and can be depended upon to properly actuate the seed-distributing mechanism of the hopper under all circumstances. This we accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of our improved corn-planter with a portion of the pole in front and a portion of the spur-wheel in the rear broken away. Fig. 2 is a plan view of our invention, and Fig. 3 is a side view of the spur-wheel and its connections broken away from the machine.

Our-invention is applied to a corn-planter comprising hoppers A A, supported by the usual runner-frame B and actuated by a transverse rock-shaft C, which connects and simultaneously operates the corn-feeding devices of each hopper. The top of the machine comprises a longitudinally-elongated rectangular wheel-frame 1/, the forward ends of the sides of which extend in front of the forward center of length of this wheel-frame a the side members thereof have suitable bearings secured thereto and depending therefrom, 1n

'cured in a suitable manner thereto.

which the axle 6 of the supporting-wheels c is journaled.

\Ve make no particular claim to any invention in the parts of the machine hereinbefore broadly alluded to, for it will be obvious that our improvements may be applied to said hereinbefore-mentioned parts whether constructed as shown in the drawings or otherwise.

In order .to actuate the shaft C, we provide the same, either at one end or both ends thereof near the hoppers A, with a downwardly-extending arm (.Z. This arm has its lower extremities connected by means of a longitudinally-disposed connecting-rod c with the longer downward-extending arm of a bell crank D, which latter is pivotally connected to a bracket secured to and depending from the sides of the frame a at points located slightly in front of the axle 7) of the supporting-frame. This bell-crank has its shorter rear wardl y extending horizontally-disposed arm engaged by the stud f, projecting laterally from the adjacent faces of a disk F, secured on the ends of a transverse shaft G, which latter is journaled in hangers 72, secured to and depending from the sides of the frame a in front of the axle of the wheel-frame the disks F the shaft (.i has sleeves l-l mounted thereon, and these sleeves have the forward ends of longitudbully-disposed reaches 1 se- These reaches preferably consist of metal bars or tubes which are given a downward semicircular bend near their forward ends, so as to enable them to pass under the axle and then extend to about under the rear cross-bar of the wheel-frame and have suitable bearings J secured to their rear extrcmities,in which the transverse connecting-shaft K is journaled. The ends of this shaft extend beyond journalsJ and have their extremities journaled in bearingsj, secured to the rear end of longer branches of the L-frame 7,1, which latter; have their forward ends bent laterally toward and secured in suitable T-couplings 1t, mounted on the reaches 1 at points midway between the plane of the axle Z) and the shaft K. Between these bearingsJ and 7' the shaft K has mounted thereon a spur-wheel M, which latter consists of a suitable central boss and equidistant spurs or pointed spokes m radiating therefrom, the periphery described by the extremities of which is of such a diameter as to enable the said spur-Wheels to revolve in a plane below the wheel-frame a. The shaft K is connected and imparts its motion to shaft Gr through the medium of sprockets and chain L, and we prefer to make both sprockets of the same diameter, so that shaft G and the disks F will make one revolution with every revolution of the wheels M. This, though, is not essential, for it might be desired in or-- der to effect the proper spacing of the seed to make shaft G revolve either faster or slower than shaft K, and consequently to differ the sizes of the sprockets in such manner as to accomplish this result. Ordinarily the spurwheels will support the weight of the reaches I and structure forming a part thereof. There are times, howeveras, for instance, when the spur-wheels come in contact with stones or other objects or when the machine is being drawn to or from the'fieldwhen it would be desirable to lift the said reaches and spurwheels, so that the points of the latter would be out of the ground. This we accomplish by a bell-crank N, pivotally connected to one side of the wheel-frame a,near the rear thereof, which has its lower end connected bya chain 0 to a sleeve P on shaft K and its upper end connected by a longitudinally-extending rod Q, to the hand-lever R, which latter is of the usual construction and is fulcrumed to the side of wheel-frame a and may be provided with a pawl that engages the segmental rack S, also secured to frame a, to hold it in any position to which it may be adjusted by the operator.

In operation the spur-wheels are dragged over the ground as the machine moves forward and by reason of the spurs'entering the ground will positively revolve shaft K and transmit its revolution to the shaftG through the medium of the sprocket-wheels and chain. Shaft G will impart its motion to the bellcrank I), and the latter through the medium of the rod 0 will impart motion to the rockshaft C on the runner-frame to actuate the feeding devices connected with the hoppers at stated intervals. As the spur-wheels travel over the field they are apt to become more or less clogged by the soil or by penetrating such objects as pieces of wood or sections of cornstalk every now and then. It is desirable that the spur-wheels be freed from these obstacles, and this we accomplish by the means of a U- shaped guard T, the ends of which are suitably secured in clips 8. s, fastened, respectively, to the reach and the L-shaped branch about as shown. These guards are bent so as to describe an evolute, and the legs thereof are made to approach and brush against the spurs in such a manner that they sweep the dirt and debris thatcollect thereon from a point near the center of the wheel out off of their extremities as the spur-wheel revolves, substantially as shown in the drawings.
